An earnest artist named William Walker, not being wholly absorbed in

the pursuit of gain, but working with enthusiasm on his own perceptions

of what is great in humanity and fitting in a nation, has for many

years devoted himself to the task of gathering and grouping together

the great men who were living in the early part of the present

century.... This is of a verity a picture of great men--men whose

instinct it was to work for the world and fight against misery: some of

them wealthy and some of them poor; with visions perchance of wealth

to come, but still working for the world's welfare as the only path

through which to ensure their own,--the race of path-finders who are

ever setting copies for the English nation to work by, and thus gain

more results by the development of national energy. Accompanying the

picture, which contains upwards of fifty portraits, some full figures,

and some more or less hidden, but all admirably grouped, there is a

volume, by Mr. Walker's son, giving a brief memoir of the salient

points of each individual history; this also is well executed, and it

forms a useful book of reference for those who would know more than the

picture can tell.... Grateful are we to men like Mr. Walker, who has

thus gathered together in groups the world's workers, with their images

and superscriptions, that men may know their benefactors, and render to

their memory that justice which was too rarely accorded to their lives.

So, all honour to the work of both the father and the son, the picture

and the book, in teaching the men of the present what they owe to men

of the past.

MECHANICS' MAGAZINE.

Perhaps no class of men have deserved more of their country and

of mankind than the great inventors and discoverers in astronomy,

chemistry, engineering and other departments of science; yet very

little is known of many of them in proportion to the acknowledged

good which has resulted from their labours. We possess works of art

commemorating the achievements of heroes in the field, and of statesmen

in parliament, but until now no work of any magnitude has ever been

executed in honour of men whose doings have laid the foundation

of our commercial prosperity. We are, however, able to state that

this can no longer be said, as Mr. Walker, of 64, Margaret-street,

Cavendish-square, has, after an extended period of labour, produced

an engraving which must remain an enduring record of our greatest era

in science--the early part of the present century. At that epoch of

time, steam, under the hands of Watt, Symington, and Trevithick, was

commencing its marvellous career; astronomy and chemistry began to

reveal their long-hidden secrets; while the discovery of vaccination,

by Jenner, had already rescued thousands from death to enjoy the

blessings left as a legacy by many a silent worker in science....

We may fairly state that we have never seen so large a body of men

arranged in a group, where it is necessary that all should, in a

measure, present their faces turned towards the spectator, so free from

that stiffness which is the general fault of works of this class. For

this, great praise is due to John Gilbert, by whom the original picture

(drawn by J. F. Skill and W. Walker) was designed. The engraving has

been executed by W. Walker and George Zobel; while in order to render

the work complete, a series of memoirs have been drawn up by Mr. W.

Walker, Jun., and furnished with a short introduction by Mr. Robert

Hunt, F.R.S., keeper of the Mining Records. We can only now say of the

book, that while many of the memoirs are necessarily brief, one, that

of Trevithick, contains the most information yet published regarding

that eminent engineer.

BUILDING NEWS.

We are glad to be able to inform our readers, that a large engraving

has just been completed by Mr. Walker, of 64, Margaret-street,

Cavendish-square, in honour of the men of science who have done so

much towards the establishment of our present commercial prosperity.

This work, which may well be called historical, represents fifty-one

illustrious men, living in the early part of the present century,

assembled in the Upper Library of the Royal Institution. The picture is

divided into three groups, and comprises authentic portraits of our

greatest inventors and discoverers in astronomy, chemistry, engineering

machinery, and other departments of science.... The grouping of so

large a number of figures must have been a difficult task; this has,

however, been successfully accomplished by John Gilbert, the designer

of the original picture, who, by a skilful combination of various

attitudes, has given both grace and ease to the figures represented.

The engraving has been executed by William Walker and George Zobel,

and the greatest care seems to have been taken to secure faithful and

authentic likenesses. The work is rendered complete by a series of

well-written memoirs, compiled to accompany the engraving. This book is

also published separately, and we should think there would be many who

would buy the memoirs although unable to purchase the engraving.

[6] At eleven years of age, Brunel's love of tools was so great that he

once pawned his hat to buy them; and at the age of twelve he is said to

have constructed different articles with as much precision as a regular

workman.

[7] Brunel had scarcely left the shores of France when he found that

he had lost his passport. This difficulty he, however, got over by

borrowing a passport from a fellow-traveller, which he copied so

exactly in every particular, down to the very seal, that it was

deemed proof against all scrutiny. He had hardly completed his task

when the American vessel was stopped by a French frigate, and all the

passengers were ordered to show their passports. Brunel, with perfect

self-possession, was the first to show his, and not the slightest doubt

was aroused as to its authenticity.

making a ship's block by this method was forty-four, and 16,000 blocks

the well-known English Reformer of the reign of George III., to whose

in 1790 he married the youngest daughter of the Rev. Dr. Kearney.

[40] The specification of this patent gives likewise the first mention

(we believe) on record of oscillating engines. Sir John Rennie,

F.R.S., in his address to the Institution of Civil Engineers, in 1846,

mentions the following passage:--"Even the objection of extra friction,

however, if tenable, is obviated _by the vibrating cylinder described

in Trevithick and Vivian's patent, in 1802_; patented by Whitty in

1813, and by Manby in 1821, by whom the first engines of the kind were

constructed."

[41] An eye-witness, who is still living, relates that on one of these

trials he saw Trevithick's steam-carriage proceeding at the rate of

twelve miles an hour.

considerable time in ascertaining the facts regarding his father's

first locomotive, states that he has no doubt the wheels of this engine

were not in any way roughed: that he has often conversed with those who

made and worked the engine; that he has their copies of the original

drawings; and that in all these cases he never heard or saw anything

which indicated that the wheels were roughed.

during this transaction, and afterwards remonstrated with Trevithick on

his folly.--The cheque offered to him has been stated by one gentleman

to have been for a far larger sum.

[47] During his residence at Glasgow, a Mason's Lodge were desirous of

possessing an organ, and Watt was asked to build it. He was totally

destitute of a musical ear, and could not distinguish one note from

the other, but he nevertheless accepted the offer; for having studied

the philosophical theory of music, he found that science would be a

substitute for want of ear. He commenced by building a small one for

Dr. Black, and then proceeded to the large one, in the building of

which he devised a number of novel expedients, such as indicators and

regulators of the strength of the blast, with various contrivances for

improving the efficiency of the stops. The qualities of this organ

when finished are said to have elicited the surprise and admiration

of musicians. During this period of his life Watt used likewise to

construct and repair guitars, flutes, and violins, and had the same

success as with his organ.--_Quarterly Review_, October, 1858.

Crown to Richard Cort, the sole surviving son of Henry Cort.

[54] The Phlogistic Theory explained the phenomena of combustion by

supposing the existence of a hypothetical substance termed Phlogiston,

the union of which with bodies made them combustible, and the

disengagement of which was the occasion of combustion.
